COLLAPSIBLE CURTAIN ROD THREADER Application filedflctober 6, 1931.. Serial No. 567,197.

This'invention relates to newand" useful improvements in a collapsible curtain rod threader.

The inventionhas for an object the con: struction of an article mentioned above which is characterized by a plurality of in+ ter-engaging shells progressively increasing A still further object of this invention is the provision of flanges upon the inter-engag ing shells to limit their extended positions.

' Another one of the objects of this invention is the pivotal mounting of the flanges,

the provision of resilient means for collapsing the flanges, and catches for holding the flanges extended when the article is not in use.

Furthermore, it is, proposed to-construct the shells of various shapes and manner so that they progressively increase in size and thus be adapted to engage on curtain rods of different sizes.

A still further object of this invention is the construction of an article of the class mentioned which is of simple, durable construction, dependable in use and eflicient in operation and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages th ereof, reference will be had to the'following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure Fig. 1 is a fragmentary perspective view of a curtain upon a. curtain rod.

Fig. 2 is a side elevational view of a threader for threading the rod to the curtain.

Fig. 3 is a front elevational view of Fig. 2.

Thecollapsible curtain rod threader, according to this invention, is for the purpose of engagement upon the end of a curtain rod 10 for the purpose of passing the rod through the customary loop 11 upon a curtain 12. The rod 10 has sharp corners 13 which cus-,

tomarily interfere with threading the rod through the loop of the curtain. The sharp corners usually engage against thematerial of the curtain and draw threads from it during threading.

theend of the rod and is composed of a plurality of inter-engaging shells progressively increasing in size.

The shells which compose the threader are indicated by reference numerals 14,15 and 16. While only three shells have been shown any number may be used. These shells are of progressively increasing size and all of them open at their rearends 17 The front end of the shell 14 is closed, this being the smallest shell. The shells are detachably connected with each other and arranged so as to be collapsible. Each of the shells have flangesl8 pivotally mounted at the top and at the bottom. Resilient means in the form of springs 19 act between the flanges and the shells for normally urging; them inwards as indicated by the dot and dash lines 20. Catch fingers 21 are stamped from the sides of the shells and capable of'engaging against the flanges 18 in the extended positionsof the latter. so asto hold the threader in the same extended position. The flanges 18 from the largest shell act against theedges of the curtain rod for insuring the maintenance of the threader on the rod. The shells 15and 16 haveopenings in their front faces for accommodating the shells 15 and 14 to form the collapsible construction.

In Fig. 7, a modification of the invention The threader, according to this invention is frictionally engaged upon has been disclosed in which the top and bot-- tom sides of each of the shells are constructed at an angle to the horizontal so that the threader increases at a more uniform rate. The inclined sides are indicated by reference numerals 22. In other respects, this construction is identical to the preferred form.

In use, the threader is frictionally engaged on the end of the curtain rod. 11 the largest shell is too large for the particular rod it is removed so that a smaller shell may engagethe rod. The removal of the shell is possible by manually forcing the fingers 521 outwards so that they release the flanges 18. The springs 19 automatically move the flanges inwards and the shells may then be separated. The shells may be collapsed by all. of the fingers 21 being moved so to release all of the flanges.

While Ihave shown and described. the preferred embodiment of my invention, it is to be understood that I do not limit myseli to the precise construction herein disclosed and the right reserved to all changes and modi fications coming within. the scope of tee invention as iined in the appended claims.

Having thus described my invention, what I claim new, and desire to secure by United States Letters Patent is:-

1. A collapsible curtain red threader, comprising inter-engaging shells progressively increasing in size and open at their rear ends forengagement upon the end of the curtain rod.

2. A collapsible curtain rod threader, comprising inter-engaging shells progressively increasing in size and open at their rear ends for engagement upon the end of the curtain rod, each of said shells being detachably connected with adjacent shells.

3. A collapsible curtain rod threader, comprising inter-engaging shells progressively increasing in size and open at their rear ends for engagement upon the end of the curtain rod, each of the shells being detachably connected with adjacent shells in a manner to allow collapsing.

i. A collapsible curtain rod threader, comprising inter-engaging shells progressively increasing in size and open at their rear ends for engagement upon the end of the curtain rod, flanges on the top and bottom sides and on the rear edges of each of said shells, and the shells co-acting with said flanges to hold the threader in extended position.

5. A collapsible curtain rod threader, comprising inter-engaging shells progressively increasing in size and open at their rear ends for engagement upon the end of the curtain rod, flanges on the top and bottom sides and on the rear edges of each of said shells, and the shells co-acting with said flanges to hold the threader in extended position, said flanges being pivotally mounted, and resilient means urging them inwards.

6. A collapsible curtain rod threader, com prising inter-engaging shells progressively increasing in size and open at their rear ends for engagement upon the end of the curtain rod, flanges on the top and bottom sides and on the rear edges of each of said shells, and the shells co-acting with said flanges to hold the threa der in extended position, said flanges being pivotally mounted, and resilient means urging them inwards, catch elements being arranged upon the shells for co-action with the flanges to hold them extended.

'7. A collapsible curtain rod threader, comprising inter engaging shells progressively increasing in size and open at their rear ends forengagement upon the end of the curtain rod, flanges on the top and bottom sides and on the rear edges of each of said shells, and the shells co-acting with said flanges to hold the threader in extended position, said flanges being pivotally mounted, and resilient means urging them inwards, catch elements being arranged upon the shells :Eor co-action with the flanges to hold them extended, said catches, comprising fingers stamped from shells.

8. A collapsible curtain rod threader, comprising inter-engaging shells progressively increasing in size and open at their rear ends for engagement upon the end of the curtain rod, the top and bottom sides of said shells being horizontal.

9. A collapsible curtain rod threader, comprising inter-engaging shells progressively increasing in size and open at their rear ends for engagement upon the end of the curtain rod, the top and bottom sides oat said shells being inclined to even off the progressive in creasing of the shells.

In testimony whereof I have affixed my signature. I
